TouZZ whom it muy concewt: i

Be it known that I, FRANCIS EDWARD OWEN, a citizen of the United States, resid-` other movable parts, and has` for its object to provide spring means cooperatii'ig with the cover and grease cup for holding the plug. cover against unscrewing after the same has been screwed into the cup, thereby obviat-ing the loss of screw covers of this character, which is a common difficulty now experienced.

A further object is to provide an annular spring having one of its ends anchored to' the periphery of the' cup and its other end terminating in a vertically disposed arm guidable in a slot in the cup and cooperating with a recess in the screw 'plug cover for holding said screw plug cover against retrograde movement after the same has been screwed to position.

lith the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter setl cover holder.

Figure l is a bottom plan view of the grease cup cover, shown in Figure 3,

Figure 5 is a side elevation of the upper portion of a grease cup f showing another form of cover holder, and part of the cover broken away to better show the structure.

Figure 6 is a top plan view of a grease cup cover showing a further form of spring,

Figure T is a detail sectional view taken on line 7 7 of Figure 6.2 y

Referring to the drawing, the numeral 1 designates' the bodyof the cup and 2 theclosure' therefor, which closure is thread ed atV 3 into the body of the grease cup in the usual manner. It' has been found` that the threaded yclosures 2 easily work loose andare lost incident'to retrograde movement thereof when the 'cups' are on inovableparts, for instanceas ,theA coniiecting rods of loconiof tives. VTo obviate this difficulty an annular springeA is provided, which spring extends around the body 1 and has its end 6 Aanchored at 7 to the outer Aperiphery of the body. The other end s of the annular springterminates in a vertically `disposedy ann 9 f which is sliglitlyllnset and dspcsed `in a vertically disposed groove lo in the side of the cup 1. The vertically disposed arm 9, when the threaded cap 2 is in closed position, engages in the recess 11 in the under side of the cap. and holds thecap against retrograde movement, but allowing the same to be rotated in either direction` when considerable power is applied thereto,

however under ordinary conditions such as j ar and vibration the spring positively holds the cap. It will be noted that by providing the annular spring, a considerable range of adjustment of the cap is possible and by disposing the arm 9 inset and in the groove 10, during the rotation of the cap, the annular spring 4 will be held against contraction and' consequent binding on the outer periphery of the body 1. i i' Referring to Figures 3 and 4: the cap 2 is held by a concentrically disposed spring arm 12, which is secured to the cap and disposed in a concentric groove 13 in the under side of the cap.` The spring arm 12 terminates in a ldownwardly extending lug 14, which co operates with a lug 15 carried by the upper end of the cup body 1, and holds the plug closure 2 against retrograde rotation until considerable tin-ning power is applied thereto, otherwise the operation is substantially the same as that shown in Figure 1.

Referring to Figure 5 wherein a further modified form is shown, the construction and operation is substantially the ,same as shown in Figures 3 and 4:, with the exception the springarm 12a is disposed in a groove 13a on theV upperside of the, plug closure 2, and'has its downwardly extend ing lug 14a, which extends through an aperture in the plug closure and coope 'ates with a lug 15a similar to the lug 15 in the form shown in Figure 3, and in the same manner as the device shown in Figure 3.

Referring to Figures 6 and 7 the plug closure 2 has its rectangula-r shaped wrench receiving portion 2 provided with an aperture 17 which is radially disposed, and which aperture has anchored in one end thereof at 18 the spring arm 19. The spring arm 19 has a limited yfreedom of movement in the aperture 17 in a vertical.

plane and has its outer end provided with a downwardly extending arm QO-which eX- tends through the notch21 in the side of the plug closure and cooperates with a lug 22 carried by the upper end of the cup l in a manner similar to that shown in Figures 3 and 5. It will be seen that when the plug closure 2a is rotated to a desired position, the spring arm will maintain the same against Irotation `in a retrograde direction until considerable power is applied thereto. In all of the devices shown the springmeans issuiciently strong to hold the closures against retrograde movement until considerable power is applied thereto, and sufficiently strong to prevent rotation under ordinary jars when the device is on a niovable part of a machine, particularly a loco motive.

From the above it will be seen that a grease cup cover holder is provided, which cover holder is positive in its operation, formed from a single piece of spring wire or material andone which may be easily and quickly applied to grease cups as at present constructed.

Theinvention having been set forth what is claimed as new and useful is 'The combination with a greasecup and a threaded closure threaded into said cup,

.of-an annular spring member surrounding the cup, one end of said spring member being anchored to thevcup, the other end of said spring member terminating inv a vertically disposed inset arm disposed in a groove ofthe cup and coopera-ting with the threaded closure. n

In testimony whereof I have signed my name to-this specification in the presence of two subscribing witnesses.
